BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a displaying device, moreparticularly to a dustproof cover of the connector slot on a displayingdevice.

[0003] 2. Description of the Related Art

[0004] In recent years, the high-tech industry has been making progressin many areas, and the development of displaying devices is also in afast growing phase. To satisfy all kinds of company needs, the researchand development of products tends to have more add-on functions,therefore many connector slots are reserved on the body of thedisplaying device. Particularly, attaining the face-to-faceteleconferencing effect needs to install a camera on the displayingdevice, and a connector slot is disposed on a predetermined position onthe top of the displaying device in order to facilitate the connectionof the camera. However, a computer system generally does not come with acamera, and the user needs to buy it as an option, or has to remove andinstall the camera anytime when the location of the meeting is changed.To prevent the connector inside the connector slot from beingcontaminated by dust or jammed by miscellaneous articles that willaffect the connection of the camera, and keep the overall appearanceneat and artistic, the prior-art displaying device uses a dustproofcover to cover the connector slot.

[0005] Refer to FIG. 1 for the dustproof cover used in the prior-artconnector slot. A connector slot 101 is disposed at the rear casing 10of the displaying device which is close to the camera (not shown in thefigure); a screw hole 102 is disposed on both ends of the connector slot101 having a groove hole 103 at the center, with a substantiallyU-shaped fixing bracket 12 is fixed to the lower periphery of the groovehole 103, and a fixing hole 122 is disposed under the groove hole 103aligning at the U-shaped fixing bracket 12. The connector 13 is invertedupward and passes through the fixing hole 122, and the flange of theconnector 13 is fixed to the lower periphery of the fixing hole 122 by ascrew 131. Further, a dustproof cover 11 having a cover body 111 in thecorresponding shape of the connector slot 101, and a through hole 112 isdisposed at the corresponding screw hole 102 on both sides of the coverbody 111, and two screw bolts 113 are passed through the two throughholes 112 and secured into the screw hole 102 in order to fix thedustproof cover 11 into the connector slot 101 and cover the slot 103above the connector 13 for the dustproof effect.

[0006] When the dustproof cover 11 is in use, a screwdriver 14 is usedto loosen the screw bolt 113, remove the dustproof cover 11, and thenpass the cable (not shown in the figure) of the camera into the groovehole 103 to connect the connector 13. When the dustproof cover is not inuse, the sequence will be reversed; removing the cable of the camera,use a screwdriver 14 to fix the dustproof cover 11. However, when theaforementioned prior-art dustproof cover 11 is in use, a screwdriver isrequired to install or remove the dustproof cover, and it is easy tolose the screw bolt, such that the dustproof cover sinks into theconnector slot 101 and its surface levels with the surface of the rearcasing. It is not easy to take the dustproof cover out, and thusinconvenient to use.

[0007]FIG. 2 shows another prior-art dustproof cover of connector slotwhich has a groove hole 201 on the rear casing 20 of the displayingdevice close to the position of the installed camera (not shown in thefigure); a bolt hole 202 on each side of the groove hole 201, and aconnector 23 is inverted upward and fixed by a substantial U-shapedbracket 22 as disclosed in the prior art. Please refer to the FIG. 1 forthe detailed structure. Since it is not related to the characteristicsof the present invention, it will not be describe here. Further, thereis a dustproof cover 21, and its cover body 211 has a through hole 212corresponsive to the bolt hole 202 at both ends of the cover body 211.Two plastic buckles 22 in tapered conical shape pass through the throughhole 212 and the bolt hole 202, fix the dustproof cover 21 onto the rearcasing 20, and cover the groove hole 201 attaining the anti-dustpurpose. When such prior-art dustproof cover is in use, although thescrewdriver is not required, sometimes it is not easy to remove thehemispherical head of the plastic buckle from the tight pressing on thesurface of the dustproof cover by the fingers. It may need to use a thinplate to hook the plastic buckle, which is definitely a shortcoming onits use. After the plastic buckle has been installed and uninstalled formany times, the plastic buckle is not only damaged easily, but also willbe lost very easily. In the meantime, the protrusion of the dustproofcover from the surface of the rear casing of the displaying device makesthe overall appearance poor looking.

DETAILED DESCRIPTION

[0018] Referring to the associated drawings, the embodiments of thepresent invention are now discussed in detail.

[0019] In FIG. 3, the dustproof cover 31 of a connector slot mainlycomprises a connector slot 301 at a rear casing 30 of the displayingdevice; a connector 33 fixed on the fixing bracket 32 below theconnector slot 301, and the dustproof cover 31 covers the connector slot301.

[0020] Wherein the connector slot 301 is disposed downward on the rearcasing 30 of the displaying device close to the installation position ofthe camera (not shown in the figure); a through hole 303 is disposed onboth ends of the connector slot 301, having a groove hole 302 at thecenter; a U-shaped fixing bracket 32 is fixed to both ends of thelateral periphery under the groove hole 302 by screws 321, and theU-shape fixing bracket 32 aligns at a fixing hole 322 under the groovehole 302, and the connector 33 with its socket facing upward and passingthrough the fixing hole 322 in the inverted position, and the flange ofthe connector 33 is fixed to the lower periphery of the fixing hole 322by screws 331.

[0021] The dustproof cover 31 of the present invention as shown in FIGS.3 and 4 comprises a cover body 316 with the shape corresponding to theshape of the connector slot 301 for the engagement, and anelasticbuckle311 is disposed on the through hole 303 at both ends of thecorresponding connector slot 301, and the elasticbuckle311 is in theshape of a sheet and is perpendicular to the surface of the cover body316 of the dustproof cover 31, and being protruded from the upper andlower surfaces of the cover body 316; a skidproof flange 312 isprotruded towards the outer periphery of the dustproof cover 31 at theupper end of the elastic buckle 311. The appropriate height protrudedfrom the cover body 316 allows the user to hook by fingers. A fixinghook 313 is disposed in the direction from the lower end of theelasticbuckle311 to the center of the cover body 316, and its lower endis protruded from the lower surface of the dustproof cover 31 such thatthe fixing hook 313 hooks to the lower outer periphery of the throughhole 303 of the connector slot 301 and fixes the dustproof cover 31 intothe connector slot 301, and covers the groove hole 302 of the connectorslot 301.

[0022] Further, please refer to FIGS. 4 and 5. To integrate each part ofthe dustproof cover 31 into a single component, the cover body 316 ofthe dustproof cover 31 has an outer hole 314 at the front side of theelasticbuckle311 and an inner hole 315 at the rear side, such that theskidproof flange 312 of the elasticbuckle311 and the fixing hook 313 canbe removed from the mold in the integral formation, and also integrallyconnects the elasticbuckle311 by the middle section of both sides andthe cover body 316. In the meantime, when the elasticbuckle311 ispressed, the fixing hook 313 can be moved easily to facilitate theinstallation and disassembling. There is no inner hole 314 or outer hole315 in the design, but it needs larger force to let the cover body 316deform in this case, such that the fixing hook 313 of theelasticbuckle311 can move and attain the purpose of installation anddisassembling.

[0023] When the dustproof cover 31 of the present invention is in use,the user just needs to use two fingers to separately hook the top of twoelastic buckles 311 of the dustproof cover 31, and the fingers will notslip away easily due to the skidproof flange 312. The upper ends of thetwo elastic buckles 311 are pushed towards the center of the dustproofcover 31 such that the lower end of the fixing hook 313 is separatedfrom the periphery of the through hole 303 and moved out from thethrough hole 303 and let the dustproof cover 31 move away from theconnector slot 301 on the rear casing 30 of the displaying device, andpass the cable of the camera (not shown in the figure) through thegroove hole 302 of the connector slot 301 and insert into the connector33 to complete the signal connection. When the connector 33 is not inuse, it needs to prevent the dust or miscellaneous articles from fallinginto the connector slot 301 and contaminating or jamming the socket ofthe connector 33 that will affect the next connection by reversing thesequence of the aforementioned connection sequence. The connector 33 isremoved from the camera cable, and then fingers are used to press theupper end of the two elastic buckles 311 of the dustproof cover 31toward the center of the dustproof cover 31, and the lower end of thefixing hook 313 moves outward and passes through the through hole 303.It lets the fixing hook 313 to hook into the periphery of the throughhole 303 such that the dustproof cover 31 can be fixed to the connectorslot 301 on the rear casing 30 of the displaying device, and makes theinstallation and disassembling easier.
